Introduction
Cisco iSCSI drivers, which reside on the server, are a key component of an iSCSI solution. These iSCSI drivers intercept small computer system interface (SCSI) commands, encapsulate them into IP packets, and redirect them to the Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2, or Cisco MDS or IPS-8. This document provides sample configurations for an IBM AIX iSCSI host to an SN 5428.
Prerequisites
Requirements
Before attempting this configuration, please ensure that you meet the following requirements:
-
Install the iSCSI driver that is compatible with your version of IBM AIX. The most current version of the driver can be found at the Cisco iSCSI Drivers (registered customers only) page on Cisco.com. Included in the driver zip (tar) file is a README.txt file which contains license agreement information, driver installation instructions, configuration instructions, and a technical overview of the driver architecture.
-
The operating system requirements and patch requirements are described in the System Requirements section of the Cisco iSCSI Driver for AIX Release Notes.
-
The Cisco iSCSI Driver version 3.3.2 for IBM AIX requires a host running the IBM AIX 4.3.3 operating system. It is recommended that the operating system be upgraded to at least AIX 4.3.3 - Maintenance Level 10. Refer to the IBM website for information on how the corresponding package can be obtained.
-
The driver also requires the following packages be installed on the host:
-
devices.fcp.disk.rte
-
devices.fcp.tape.rte
The above packages are present on the AIX operating system CDs.
-
-
The Cisco iSCSI Driver version 3.3.2 for IBM AIX is compatible with Cisco SN 5400 series storage routers running software version 3.x or greater. It is not compatible with Cisco SN 5400 series storage routers running software versions 1.x or 2.x.

Background Information
SCSI routing provides IP hosts with access to Fibre Channel (FC) storage devices as if the storage devices were directly attached to the hosts, with access to devices being managed primarily in the SN 5428 storage router. An iSCSI target is an arbitrary name for a group of physical storage devices. The iSCSI targets are created and mapped to physical storage devices attached to the SN 5428. The storage router presents the iSCSI targets to IP hosts as if the physical storage devices were directly attached to the hosts. With SCSI routing, storage devices are not aware of each IP host; the storage devices are aware of the SN 5428 and respond to it as if it were one FC host.
SCSI routing consists of routing SCSI requests and responses between hosts in an IP network and FC storage. Each host that requires IP access to storage via an SN 5428 storage router needs to have a compatible iSCSI driver installed. Using the iSCSI protocol, the iSCSI driver allows an IP host to transport SCSI requests and responses over an IP network. From the perspective of a host operating system, the iSCSI driver appears to be a SCSI or FC driver for a peripheral channel in the host.
SCSI routing consists of the following main actions:
-
Transporting SCSI requests and responses over an IP network between the hosts and the SN 5428 storage router.
-
Routing SCSI requests and responses between hosts on an IP network and FC storage.
-
Transporting SCSI requests and responses between the SN 5428 storage router and FC storage.
SCSI routing occurs in the SN 5428 storage router through the mapping of physical storage devices to iSCSI targets. An iSCSI target is an arbitrary name for a group of physical storage devices. You can map an iSCSI target to multiple physical devices. An iSCSI target always contains at least one Logical Unit Number (LUN). Each LUN on an iSCSI target is mapped to a single LUN on a physical storage target.
You can choose either of two types of storage mapping: target-and-LUN mapping or target-only mapping. Target-and-LUN mapping maps an iSCSI target and LUN combination to a physical storage target and LUN combination. Target-only mapping maps an iSCSI target to a physical storage target and its LUNs.
With target-only mapping, an iSCSI target name is specified and mapped to the physical storage address of a storage controller only: a World Wide Port Name (WWPN). Any LUNs that are available in the storage controller are made available as iSCSI LUNs and are numbered the same as the LUNs in the storage controller. For example, if an iSCSI target specified as Webserver2000 were mapped to the physical storage address WWPN 3100112233445577, and LUNs 0 through 2 were available in that controller, then those LUNs would become available as three iSCSI LUNs. An iSCSI driver would see the iSCSI target named Webserver2000 as a controller with three iSCSI LUNs identified as LUN 0, LUN 1, and LUN 2. Each iSCSI LUN would appear as a separate storage device to a host.
With target-and-LUN mapping, an iSCSI target name and iSCSI LUN number are specified and mapped to the physical storage address of one LUN: either a WWPN and LUN combination, a LUN ID (unique LUN identifier), or a LUN serial number. If the LUN is available, it is made available as an iSCSI LUN and numbered with the iSCSI LUN number specified. For example, if an iSCSI target and iSCSI LUN specified as Database, LUN 9 were mapped to the physical storage address, WWPN 3100112233445566, LUN 12, then LUN 12 would be available as one iSCSI LUN. An iSCSI driver would see the iSCSI target named Database, with one iSCSI LUN identified as LUN 9. The iSCSI LUN would appear as one storage device to a host.
Access for SCSI routing is controlled in the IP hosts and the storage router. In an IP host, the iSCSI driver is configured with the Gigabit Ethernet (GE) IP address of the SCSI routing instance in the storage router with which the host is to transport SCSI requests and responses. In a storage router, access is controlled through an access list and a VLAN identifier (VID) number of the hosts. Additionally, access can be further controlled in the SN 5428 through authentication.

!--- The iscsi.conf file must be modified on the AIX host, as shown below.
Ades# more iscsi.conf
# iSCSI configuration file - see iscsi.conf(5)
# Authentication Settings
# -----------------------
# You may configure a default Username and Password to use for CHAP
# authentication by specifying the Global username and password parameters
# in the format as mentioned below. These entries will need to precede any
# "DiscoveryAddress" entries if authentication needs to be enabled for all the
# iSCSI targets.
#
# Example:
#
#Username=alice
#Password=nty57nbe
# or
#OutgoingUsername=alice
#OutgoingPassword=nty57nbe
#
# The "OutgoingUsername" will specify the username to be sent to the target
# for login authentication. The "OutgoingPassword" is the CHAP secret password
# to be used when sending challenge responses to the target.
#
#
# You may configure CHAP authentication settings that will apply to every
# target discovered at a particular address by adding "OutgoingUsername=u"
# and "OutgoingPassword=p" entries indented below the "DiscoveryAddress"
# entry they apply to.
#
# Example:
#
#DiscoveryAddress=192.168.10.94
# OutgoingUsername=alice
# OutgoingPassword=nty57nbe
#
# or
#
#DiscoveryAddress=192.168.10.94
# Username=alice
# Password=nty57nbe
DiscoveryAddress=10.48.69.202
!--- Configure the IP address of the GE interface that accepts iSCSI requests
!--- from your host.
# LUN Settings
# ------------
# The LUN settings could be specified per TargetName or for all the targets
# whose TargetNames are mentioned in the configuration file. If no TargetName
# is present in the configuration file, the lun(s) will be configured for
# all the available iSCSI targets.
# The LUN settings can be specified in the following 3 formats:
# LUN=<lun_number>
# LUNs=<lun_range>
# LUNs=<lun_list>
# Continuous Discovery settings
# -----------------------------
# You can configure discovery session to be kept open by setting
# Continuous=yes(default setting). Set Continuous=no to close
# the discovery session, once the discovery is over.
#
#Continuous=yes
#Continuous=no
Continuous=yes
# TargetName Specific Settings
# ----------------------------
# Target-specific settings should be entered below the respective "TargetName"
# entries. If Multipath is enabled, then these target-specific settings will be
# be applicable for all iSCSI sessions to this target.
#
# If settings under "Subnet" entry are conflicting with settings under
# "TargetName" entry, the settings under "Subnet" will be considered.
#
#TargetName=iqn.1987-05.com.cisco:00.0d1d898e8d66.t0
#
# The TargetName Settings can have the following entries specific to a target.
#
# 1) iSCSI Operational Parameter settings
# 2) Timeout Settings
# 3) TCP Settings
# 4) Portal Failover Settings
# 5) Multipath Settings
# 6) LUN settings
# 7) PreferredSubnet and PreferredPortal Settings

!--- You can find the target names in the output of the
!--- show scsirouter name
command on SN 5428.
# NOTES:
# ------
# If any of the configuration parameters are not mentioned under Configuration
# type DiscoveryAddress, TargetName or Subnet, global values will be
# considered if they are specified, else default settings will apply for these
# configuration parameters.
#
# All entries specified below any of the Configuration types must be indented
# by a whitespace character or a tab to be considered local to a category. If
# they are specified in the 1st column they are by default considered as global

!--- AIX assigns SCSI device names and device nodes dynamically whenever a SCSI
!--- logical unit is detected. Variations in process scheduling may result in
!--- iSCSI targets being mapped to different SCSI device nodes every time the
!--- driver is started.
!--- The "Persistent target binding" feature guarantees that a device node
!--- always maps to the same physical storage device from one reboot to the next.
!--- To achieve this, AIX iSCSI driver binds:
!--- a) an iSCSI TargetName to a SCSI target ID
!--- b) a TargetID,LunID to a disk name.
!--- The aforementioned bindings are stored in the files /etc/iscsi.bindings and
!--- /etc/iscsi_device_bindings, respectively.
!--- If the files do not exist, they will be created when the driver is started.
!--- If an entry exists for a discovered target (in /etc/iscsi.bindings), the
!--- SCSI target ID from the entry is assigned to the target. If no entry exists
!--- for a discovered target, an entry is written to the file.
!--- The BusId field is included for compatibility with other UNIX operating
!--- systems. For AIX, the BusId value will always be zero.
!--- Note that the /etc/iscsi.bindings and /etc/iscsi_device_bindings files will
!--- permanently contain entries for all iSCSI targets ever logged into from this
!--- host. If a target is no longer available to a host, you can manually edit the
!--- files and remove entries so the obsolete target no longer consumes a SCSI
!--- target ID and device name(s) (this is normally not needed, because the driver
!--- can maintain up to 64 different bindings). If you know the iSCSI name of a
!--- target in advance and you want it to be assigned a particular SCSI target ID,
!--- you can add an entry manually. Similarly, if you wish a particular name be
!--- assigned for a TargetID,LunID then you must manually add an entry into the
!--- second file. You should stop the iSCSI driver before editing the
!--- aforementioned files. Be careful to keep an entire entry on a single line,
!--- with only space characters between the three fields. Do not use a target
!--- ID number that already exists in the file.
!--- *****************************************************************************
!--- NOTE: iSCSI driver versions earlier than 3.2 use the file /etc/iscsi_bindings
!--- instead of /etc/iscsi.bindings and /etc/iscsi_device_bindings. The
!--- first time you start the new driver version, it will convert the old
!--- file to the new file format and create entries in the new files. Your
!--- old file will be renamed /etc/iscsi_bindings.old in case you need it
!--- for reference purposes.
!--- *****************************************************************************
!--- To manually start the iSCSI driver, issue the following command:
/etc/rc.iscsi
!--- When the driver is started, the startup script will automatically mount the
!--- partitions listed in /etc/filesystems.iscsi. To see the iSCSI devices
!--- currently available, issue the following command:
/usr/bin/iscsi-ls -l
!--- To manually stop the iSCSI driver, issue the following command:
/etc/iscsi.clean rem
!--- When the driver is stopped, the shutdown script will attempt to unmount
!--- file systems listed in /etc/filesystems.iscsi. If the file systems are in use,
!--- the script will fail to unmount them. The applications using them must first
!--- be stopped and the script must be re-run. File systems not listed in
!--- /etc/filesystems.iscsi will not be unmounted by the script and should be
!--- manually unmounted prior to a system shutdown.
!--- It is very important to unmount all file systems on iSCSI devices before
!--- stopping the iSCSI driver. If the iSCSI driver is stopped while iSCSI devices
!--- are mounted, buffered writes may not be committed to disk and file system
!--- corruption may occur.
!--- ------------LOG MESSAGES------------
!--- The iSCSI driver contains components in the kernel and user level utilities.
!--- The log messages from these components are sent to syslog. Based on the
!--- syslog configuration on the AIX host, the messages will be sent to the
!--- appropriate destination. iSCSI driver messages can be received from the
!--- following facilities:
!--- 1. kernel
!--- 2. daemon (iscsid)
!--- 3. user (iscsiactlun)
!--- The log messages from the iSCSI driver are redirected to the location as
!--- specified during the syslogd configuration. For example, consider a
!--- /etc/syslog.conf file that has the following entries:
!--- kern.debug /dev/console
!--- user.debug /usr/adm/ras/iscsi.log
!--- All the kernel messages will go to the console and all the user
!--- messages will go to /usr/adm/ras/iscsi.log.
